T0 ALL WHOM IT MAY CONCERN: p p

' Be it known that I, ISAAC LAMPLUGH, of Peoria city, in the county of Peoria, and in the State alf-Illinois, have invented certain new and useful Improvements in Punches; and do hereby declare that the following-is a full, clear, and exact description thereof, reference being had to the accomponyiugdrawings, and to the letters of reference marked thereon. I f

In the annexed drawings, making part of this speciication, A A' represent the end-pieces of the frame of this pun'ch. There are two of these end-pieces at 4each end ofthe frame, placed close together, so as to vembrace between them the bar B and the levers F F'. These bars are spread or'separated at their lower ends so as to form four legs for the frame to sit upon. C represents a cross-bar, cohnectngthe bars A A' together attheir upper ends. F represents an elbow-lever, which is' pivoted at its elbow between the end-pieces A'. A connectng bar, E, connects onearm oilever F to the'punch-lever D, as seen, being pivoted to both. G- represents a bar, which connects the other arm of lever F to a lever, H. The lower end of lever His pivoted to an arm,

I, which projects from the frame. Two ears, J, are formed upon or secured to the lever D, and between said ears the punch is secured. K represents the die, which is secured directly under the punch upon the bar B.

- A pin,e, passes through'the lend-pieces A, and thronghleverl), at the point -where it passes between them, and

forms a fulcrum for said lever. F', G', H', I', and E' represent parts which correspond with those of like'letters just described, but are situated and secured to the opposite end'of the frame. In order to move the punch by p lever H it is necessary to withdraw the'` pin e, and then the fulcru'mof lever D Vchanges `to its other end.` "It Y will be readily seen that much more poweris gainedby the use o f lever K than bythe use of lever H', and consequently, when I wish to punch an article requiring butlittle power Von the lever, 'I use the lever H', but in i punching holes wherea great deal of power is required, I use the lever H.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is- The improved punching-apparatus, consisting of the several devices, constructed, `combined, and arranged in the manner and for the purposes-herein setforth. V

In testimony that I claimthe foregoing, I'have hereuutoset my hand, this 2d day of August, 1867.
